Well done, I certainly remember that first 20 minute run, that was the time that I really began to think "oooh I feel like I could be a runner". I got back from that particular run on an absolute high....felt on top of the world and you could not shut me up. On my walk home I wanted to tell everyone of my achievement! In fact I burst into a sprint for the last 100metres! Not done that kinda thing for about 35 years!
